How Installing Energy-Efficient Windows in Windham Saves You Money

There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
• Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Windham

Windows come in varying shapes, purposes and styles, so costs and services will differ remarkably based on several factors. Below, we detail the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

Even though the typical cost to install one window is about $600, it can range from $200 to $1,200. How much it will cost depends on several factors, including the location of your home, size, type, number of windows, material and more.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $457 a year on your energy bills in Windham.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the complete window, including the sill, frame and trim. A pocket installation entails replacing a window within the old frame. This means instead of tearing out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which kind of window installation service you need, your installer can assist you. Typically, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, professionalism, quality of installation, warranty, cost and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
